Why shouldn't you take alcohol and melatonin together?
20 November 2024
Melatonin is a popular food supplement, often used as support for falling asleep. Alcohol, on the other hand, is a widely consumed substance that many people find relaxing. Taking alcohol and melatonin at the same time, however, can have negative effects on the body and is not advisable. In this article we explain why this combination is problematic and what risks it carries.
What is melatonin?
Melatonin is a natural hormone produced by the pineal gland in the brain. It plays a decisive role in regulating the sleep-wake rhythm and signals to the body when it is time to sleep. According to the European Food Safety Authority (EFSA), from 1 mg melatonin contributes to the reduction of time taken to fall asleep. Many people therefore use melatonin preparations as evening support, particularly with jet lag or during demanding periods.
How does alcohol affect sleep?
Alcohol is often mistakenly regarded as a sleep aid, since it can have a relaxing effect at first. That impression is deceptive. Alcohol:
- Disrupts sleep architecture, particularly the REM phases that matter for recovery.
- Can lead to restless sleep and frequent night-time waking.
- Promotes dehydration and worsens snoring or sleep apnoea.
Why is combining alcohol and melatonin problematic?
1. Reduced effect of melatonin
Alcohol can impair the effectiveness of melatonin. Because alcohol disrupts the natural processes of the sleep cycle, melatonin may not fully deliver its contribution to reducing the time taken to fall asleep. This often means the hoped-for benefit is not achieved.
2. Increased drowsiness and confusion
Melatonin can make you sleepy; combined with alcohol this effect can be amplified. That can lead to excessive drowsiness, confusion and an increased risk of accidents, especially if you have to be active after taking alcohol and melatonin (driving or operating machinery, for example).
3. Possible side effects
The combination can intensify accompanying complaints, including:
- Dizziness
- Nausea
- Headaches
- Greater grogginess the next morning
4. Strain on the liver
Both alcohol and melatonin are broken down by the liver. Taking them together can place additional strain on the organ and potentially slow down detoxification, which can strengthen the effect of alcohol and cause unwanted complaints.
5. Longer time to fall asleep
While melatonin contributes to the reduction of time taken to fall asleep, alcohol can have the opposite effect and make falling asleep harder, defeating the purpose of taking it.
What can happen if alcohol and melatonin are taken together?
- Less restorative night's rest: alcohol can make the night less restful despite falling asleep quickly.
- Increased risk of falls or accidents: the combination intensifies drowsiness and can impair coordination.
- Disruption of natural sleep regulation: regularly combining with alcohol can interfere with the body's own sleep regulation.
- Development of tolerance: over time, higher doses might be needed to achieve the desired effect, which in turn intensifies side effects.
Recommendations for safe use of melatonin
- Avoid alcohol before and after taking melatonin. Give your body at least 2–3 hours to break down the alcohol before taking melatonin.
- Stick to the recommended dosage. More on this in our guide to possible melatonin side effects.
- Rely on healthy sleep habits. A dark, quiet and cool environment supports sleep naturally.
Conclusion
Taking alcohol and melatonin at the same time is not a good idea. Alcohol can impair the effect of melatonin, disturb night-time recovery and intensify side effects. If you use melatonin as evening support, it is better to avoid alcohol. A considered approach to both substances is the sensible course.
